For the benefit of those like myself who need it spelled out in basic terms ...
- what is being referenced above is copy of a bit of code from
yourgallery/themes/sample/theme.php
to your custom theme.
So, further spelled out, the steps I have taken for success are as follows:
1. Custom Theme ==> create one by duplicating the theme files (for me that is the rainy_day theme which I copied with the name rainy_day_01)
2. Get Code ==> from yourgallery/themes/sample/theme.php
copy the bit of code that begins with
/******************************************************************************
** Section <<<theme_main_menu>>> - START
******************************************************************************/
and ends with
/******************************************************************************
** Section <<<theme_main_menu>>> - END
******************************************************************************/
and paste that into your custom theme.
for me that is:
yourgallery/themes/rainy_day_01/theme.php
I pasted just before the
?>
at the end of the file.
3. for my case, to
modify the target URL of the "Contact" button:
in yourgallery/themes/rainy_day_01/theme.php I modified the line
'{CONTACT_TGT}' => "contact.php",
with the target URL I needed
http://seawolfadventures.net/contact/index.htmlinstead of "contact.php"
'{CONTACT_TGT}' => "http://seawolfadventures.net/contact/index.html",
4. Activate the theme ==> Logged in as admin I selected the rainy_day_01 theme.
Done.
If things go wrong then of course you can replace the clean copy of
rainy_day/theme.php
with
rainy_day_01/theme.php
Hope this helps and hopefully I have represented all my steps correctly. I'm happy to clarify for others if asked.
Now that I see this example it makes sense in the documentation, so please don't take this as a criticism of the documentation but rather just an example implementation of it.
I thank all on the forum who helped me learn this.
